The Research On The Application Of The Queueing Theory In The Multi-thread Web Service System

The web service system is a important application in the internet. To develop the web service system usually using the technology of multi-thread. In the practice of developing the multi-thread web service system, the numuber of thread is a importmat factor to the performance of multi-thread web service system. Therefore, using mathematic model to describe the multi-thread web service system can result in the best parameter design and undoubtedly has economical value and practical significance.In this dissertation, the queueing theory is used in the multi-thread web service system. The thread in the multi-thread web service system is regard as the server of the queueing system, and build up the multi-server and lossing M/M/n/n queuing model corresponding to multi-thread web service system, educe the stationry distributing and the primay target parameter of the multi-thread web service system. The dissertation also makes use of the Maple software to compose calculation procedure, has gained the corresponding target parameter. Making use of the wishes model to optimize has obtained optimal thread's number let the rate of lossing p_n < 0.02 and advanced the efficiency of thread.
